See this link for more details. The problem is that excess glycerin present in home brewed biodiesel can clog the fiters. Since glycerin is soap, it's basically soap clogging the exhaust filters. We will have to wait and see what impact the urea injection will have and if high percentages of commercially refined biodiesel will have. This is the same reason that bluetec is compatible only with the new ultra low sulphur diesel. (This is what almost all pumps have had for a while)
The big irony is that since biodiesel is so clean, the filters aren't as essential to producing clean emissions. The problem is when you use lower percentages of biodiesel or mostly fossil diesel.
Just a quick question to see if anyone runs biodiesel in a PD engine and what if any, problems have occurred?
I've heard bio gunks up the nozzles and causes bad running? And vw only recommends a small amount be used.
Thanks in advance for the help
Used to make BioD but DinoD is just too cheap. I made BioD for my two trucks and Mercedes 93 300d (350K before it died) but with Diesel at 1.98 a gallon I can't make it that cheap. I'd like to run my 2010 Jetta SW TDI on 10% BioD just for the performance and cleaning properties. Anybody...
I live near a peanut area and read that some farmers use a seed press to make their own oil then cut it with ten to twenty percent gasoline and kerosene. I used this one tank full in my Detroit 6.5 and my 93 2.5L 300D Mercedes. has anyone tried this in a TDI or other common rail motor?
I pulled up to a Murphy gas station with a diesel pump. ON the pump it had a disclaimer that said the fuel contained Biodiesel and that I should consult my engine manufacturer before using, etc. The price was .10 cents cheaper than the diesel at race trac down the road, but I didn't bother...
